This Unity tutorial will discuss the process of creating a custom Graphical User Interface for our mobile game on the Android tablet. Through out these lessons, we'll create our own custom scripts to create the exact behavior we want from our user interface and how we implement those to work with our Android tablet. We'll create buttons that will allow us to fire, reload, and swap our weapons. We'll also create the functionality to give the player feedback on how much ammo, time, and health they have during the game
